Any ideas for her birth?
4 Mary Walsh baptisms in Aghaboe Parish in that general time frame.
Mary to William Walsh and Honor Fitzpatrick 26th January 1834
Mary to Thomas Walsh and Elen Kelly 2nd December 1838
Mary to Patrick Walsh and Mary Collins 31st July 1841
Mary to Tom Walsh and Mary Culleton 5th January 1844
That's just from transcripts so didn't look at register at NLI to see what address if any given etc.
